Cell barring procedure in NTN

ABSTRACT

A UE may receive, from at least one cell via at least one bit in a MIB or a SIB, a barring indication based on a supported network of the at least one cell and a supported network of the UE. The supported network of the at least one cell may correspond to a TN or an NTN, and the supported network of the UE may correspond to a TN or an NTN. The UE may skip, based on the received barring indication, a selection of the at least one cell for communication. Accordingly, the UE may not camp on the at least one cell. The barring indication for NTN-supporting UEs and for TN-supporting UEs may be separately indicated via the MIB or the SIB.

BACKGROUND Technical Field

The present disclosure relates generally to communication systems, andmore particularly, to barring access to a cell in a wirelesscommunication system.

INTRODUCTION

Wireless communication systems are widely deployed to provide varioustelecommunication services such as telephony, video, data, messaging,and broadcasts. Typical wireless communication systems may employmultiple-access technologies capable of supporting communication withmultiple users by sharing available system resources. Examples of suchmultiple-access technologies include code division multiple access(CDMA) systems, time division multiple access (TDMA) systems, frequencydivision multiple access (FDMA) systems, orthogonal frequency divisionmultiple access (OFDMA) systems, single-carrier frequency divisionmultiple access (SC-FDMA) systems, and time division synchronous codedivision multiple access (TD-SCDMA) systems.

These multiple access technologies have been adopted in varioustelecommunication standards to provide a common protocol that enablesdifferent wireless devices to communicate on a municipal, national,regional, and even global level. An example telecommunication standardis 5G New Radio (NR). 5G NR is part of a continuous mobile broadbandevolution promulgated by Third Generation Partnership Project (3GPP) tomeet new requirements associated with latency, reliability, security,scalability (e.g., with Internet of Things (IoT)), and otherrequirements. 5G NR includes services associated with enhanced mobilebroadband (eMBB), massive machine type communications (mMTC), andultra-reliable low latency communications (URLLC). Some aspects of 5G NRmay be based on the 4G Long Term Evolution (LTE) standard. There existsa need for further improvements in 5G NR technology. These improvementsmay also be applicable to other multi-access technologies and thetelecommunication standards that employ these technologies.

DETAILED DESCRIPTION

The detailed description set forth below in connection with the appendeddrawings is intended as a description of various configurations and isnot intended to represent the only configurations in which the conceptsdescribed herein may be practiced. The detailed description includesspecific details for the purpose of providing a thorough understandingof various concepts. However, it will be apparent to those skilled inthe art that these concepts may be practiced without these specificdetails. In some instances, well known structures and components areshown in block diagram form in order to avoid obscuring such concepts.

Several aspects of telecommunication systems will now be presented withreference to various apparatus and methods. These apparatus and methodswill be described in the following detailed description and illustratedin the accompanying drawings by various blocks, components, circuits,processes, algorithms, etc. (collectively referred to as “elements”).These elements may be implemented using electronic hardware, computersoftware, or any combination thereof. Whether such elements areimplemented as hardware or software depends upon the particularapplication and design constraints imposed on the overall system.

By way of example, an element, or any portion of an element, or anycombination of elements may be implemented as a “processing system” thatincludes one or more processors. Examples of processors includemicroprocessors, microcontrollers, graphics processing units (GPUs),central processing units (CPUs), application processors, digital signalprocessors (DSPs), reduced instruction set computing (RISC) processors,systems on a chip (SoC), baseband processors, field programmable gatearrays (FPGAs), programmable logic devices (PLDs), state machines, gatedlogic, discrete hardware circuits, and other suitable hardwareconfigured to perform the various functionality described throughoutthis disclosure. One or more processors in the processing system mayexecute software. Software shall be construed broadly to meaninstructions, instruction sets, code, code segments, program code,programs, subprograms, software components, applications, softwareapplications, software packages, routines, subroutines, objects,executables, threads of execution, procedures, functions, etc., whetherreferred to as software, firmware, middleware, microcode, hardwaredescription language, or otherwise.

Accordingly, in one or more example embodiments, the functions describedmay be implemented in hardware, software, or any combination thereof. Ifimplemented in software, the functions may be stored on or encoded asone or more instructions or code on a computer-readable medium.Computer-readable media includes computer storage media. Storage mediamay be any available media that can be accessed by a computer. By way ofexample, and not limitation, such computer-readable media can comprise arandom-access memory (RAM), a read-only memory (ROM), an electricallyerasable programmable ROM (EEPROM), optical disk storage, magnetic diskstorage, other magnetic storage devices, combinations of theaforementioned types of computer-readable media, or any other mediumthat can be used to store computer executable code in the form ofinstructions or data structures that can be accessed by a computer.

FIG. 1 is a diagram illustrating an example of a wireless communicationssystem and an access network 100. The wireless communications system(also referred to as a wireless wide area network (WWAN)) includes basestations 102, UEs 104, an Evolved Packet Core (EPC) 160, and anothercore network 190 (e.g., a 5G Core (5GC)). The base stations 102 mayinclude macrocells (high power cellular base station) and/or small cells(low power cellular base station). The macrocells include base stations.The small cells include femtocells, picocells, and microcells.

The base stations 102 configured for 4G LTE (collectively referred to asEvolved Universal Mobile Telecommunications System (UMTS) TerrestrialRadio Access Network (E-UTRAN)) may interface with the EPC 160 throughfirst backhaul links 132 (e.g., S1 interface). The base stations 102configured for 5G NR (collectively referred to as Next Generation RAN(NG-RAN)) may interface with core network 190 through second backhaullinks 184. In addition to other functions, the base stations 102 mayperform one or more of the following functions: transfer of user data,radio channel ciphering and deciphering, integrity protection, headercompression, mobility control functions (e.g., handover, dualconnectivity), inter-cell interference coordination, connection setupand release, load balancing, distribution for non-access stratum (NAS)messages, NAS node selection, synchronization, radio access network(RAN) sharing, multimedia broadcast multicast service (MBMS), subscriberand equipment trace, RAN information management (RIM), paging,positioning, and delivery of warning messages. The base stations 102 maycommunicate directly or indirectly (e.g., through the EPC 160 or corenetwork 190) with each other over third backhaul links 134 (e.g., X2interface). The first backhaul links 132, the second backhaul links 184,and the third backhaul links 134 may be wired or wireless.

The base stations 102 may wirelessly communicate with the UEs 104. Eachof the base stations 102 may provide communication coverage for arespective geographic coverage area 110. There may be overlappinggeographic coverage areas 110. For example, the small cell 102′ may havea coverage area 110′ that overlaps the coverage area 110 of one or moremacro base stations 102. A network that includes both small cell andmacrocells may be known as a heterogeneous network. A heterogeneousnetwork may also include Home Evolved Node Bs (eNBs) (HeNBs), which mayprovide service to a restricted group known as a closed subscriber group(CSG). The communication links 120 between the base stations 102 and theUEs 104 may include uplink (UL) (also referred to as reverse link)transmissions from a UE 104 to a base station 102 and/or downlink (DL)(also referred to as forward link) transmissions from a base station 102to a UE 104. The communication links 120 may use multiple-input andmultiple-output (MIMO) antenna technology, including spatialmultiplexing, beamforming, and/or transmit diversity. The communicationlinks may be through one or more carriers. The base stations 102/UEs 104may use spectrum up to Y MHz (e.g., 5, 10, 15, 20, 100, 400, etc. MHz)bandwidth per carrier allocated in a carrier aggregation of up to atotal of Yx MHz (x component carriers) used for transmission in eachdirection. The carriers may or may not be adjacent to each other.Allocation of carriers may be asymmetric with respect to DL and UL(e.g., more or fewer carriers may be allocated for DL than for UL). Thecomponent carriers may include a primary component carrier and one ormore secondary component carriers. A primary component carrier may bereferred to as a primary cell (PCell) and a secondary component carriermay be referred to as a secondary cell (SCell).

Certain UEs 104 may communicate with each other using device-to-device(D2D) communication link 158. The D2D communication link 158 may use theDL/UL WWAN spectrum. The D2D communication link 158 may use one or moresidelink channels, such as a physical sidelink broadcast channel(PSBCH), a physical sidelink discovery channel (PSDCH), a physicalsidelink shared channel (PSSCH), and a physical sidelink control channel(PSCCH). D2D communication may be through a variety of wireless D2Dcommunications systems, such as for example, WiMedia, Bluetooth, ZigBee,Wi-Fi based on the Institute of Electrical and Electronics Engineers(IEEE) 802.11 standard, LTE, or NR.

The wireless communications system may further include a Wi-Fi accesspoint (AP) 150 in communication with Wi-Fi stations (STAs) 152 viacommunication links 154, e.g., in a 5 GHz unlicensed frequency spectrumor the like. When communicating in an unlicensed frequency spectrum, theSTAs 152/AP 150 may perform a clear channel assessment (CCA) prior tocommunicating in order to determine whether the channel is available.

The small cell 102′ may operate in a licensed and/or an unlicensedfrequency spectrum. When operating in an unlicensed frequency spectrum,the small cell 102′ may employ NR and use the same unlicensed frequencyspectrum (e.g., 5 GHz, or the like) as used by the Wi-Fi AP 150. Thesmall cell 102′, employing NR in an unlicensed frequency spectrum, mayboost coverage to and/or increase capacity of the access network.

The electromagnetic spectrum is often subdivided, based onfrequency/wavelength, into various classes, bands, channels, etc. In 5GNR, two initial operating bands have been identified as frequency rangedesignations FR1 (410 MHz-7.125 GHz) and FR2 (24.25 GHz-52.6 GHz).Although a portion of FR1 is greater than 6 GHz, FR1 is often referredto (interchangeably) as a “sub-6 GHz” band in various documents andarticles. A similar nomenclature issue sometimes occurs with regard toFR2, which is often referred to (interchangeably) as a “millimeter wave”band in documents and articles, despite being different from theextremely high frequency (EHF) band (30 GHz-300 GHz) which is identifiedby the International Telecommunications Union (ITU) as a “millimeterwave” band.

The frequencies between FR1 and FR2 are often referred to as mid-bandfrequencies. Recent 5G NR studies have identified an operating band forthese mid-band frequencies as frequency range designation FR3 (7.125GHz-24.25 GHz). Frequency bands falling within FR3 may inherit FR1characteristics and/or FR2 characteristics, and thus may effectivelyextend features of FR1 and/or FR2 into mid-band frequencies. Inaddition, higher frequency bands are currently being explored to extend5G NR operation beyond 52.6 GHz. For example, three higher operatingbands have been identified as frequency range designations FR4a or FR4-1(52.6 GHz-71 GHz), FR4 (52.6 GHz-114.25 GHz), and FR5 (114.25 GHz-300GHz). Each of these higher frequency bands falls within the EHF band.

With the above aspects in mind, unless specifically stated otherwise, itshould be understood that the term “sub-6 GHz” or the like if usedherein may broadly represent frequencies that may be less than 6 GHz,may be within FR1, or may include mid-band frequencies. Further, unlessspecifically stated otherwise, it should be understood that the term“millimeter wave” or the like if used herein may broadly representfrequencies that may include mid-band frequencies, may be within FR2,FR4, FR4-a or FR4-1, and/or FR5, or may be within the EHF band.

A base station 102, whether a small cell 102′ or a large cell (e.g.,macro base station), may include and/or be referred to as an eNB, gNodeB(gNB), or another type of base station. Some base stations, such as gNB180 may operate in a traditional sub 6 GHz spectrum, in millimeter wavefrequencies, and/or near millimeter wave frequencies in communicationwith the UE 104. When the gNB 180 operates in millimeter wave or nearmillimeter wave frequencies, the gNB 180 may be referred to as amillimeter wave base station. The millimeter wave base station 180 mayutilize beamforming 182 with the UE 104 to compensate for the path lossand short range. The base station 180 and the UE 104 may each include aplurality of antennas, such as antenna elements, antenna panels, and/orantenna arrays to facilitate the beamforming.

The base station 180 may transmit a beamformed signal to the UE 104 inone or more transmit directions 182′. The UE 104 may receive thebeamformed signal from the base station 180 in one or more receivedirections 182″. The UE 104 may also transmit a beamformed signal to thebase station 180 in one or more transmit directions. The base station180 may receive the beamformed signal from the UE 104 in one or morereceive directions. The base station 180/UE 104 may perform beamtraining to determine the best receive and transmit directions for eachof the base station 180/UE 104. The transmit and receive directions forthe base station 180 may or may not be the same. The transmit andreceive directions for the UE 104 may or may not be the same.

The EPC 160 may include a Mobility Management Entity (MME) 162, otherMMEs 164, a Serving Gateway 166, a Multimedia Broadcast MulticastService (MBMS) Gateway 168, a Broadcast Multicast Service Center (BM-SC)170, and a Packet Data Network (PDN) Gateway 172. The MME 162 may be incommunication with a Home Subscriber Server (HSS) 174. The MME 162 isthe control node that processes the signaling between the UEs 104 andthe EPC 160. Generally, the MME 162 provides bearer and connectionmanagement. All user Internet protocol (IP) packets are transferredthrough the Serving Gateway 166, which itself is connected to the PDNGateway 172. The PDN Gateway 172 provides UE IP address allocation aswell as other functions. The PDN Gateway 172 and the BM-SC 170 areconnected to the IP Services 176. The IP Services 176 may include theInternet, an intranet, an IP Multimedia Subsystem (IMS), a PS StreamingService, and/or other IP services. The BM-SC 170 may provide functionsfor MBMS user service provisioning and delivery. The BM-SC 170 may serveas an entry point for content provider MBMS transmission, may be used toauthorize and initiate MBMS Bearer Services within a public land mobilenetwork (PLMN), and may be used to schedule MBMS transmissions. The MBMSGateway 168 may be used to distribute MBMS traffic to the base stations102 belonging to a Multicast Broadcast Single Frequency Network (MBSFN)area broadcasting a particular service, and may be responsible forsession management (start/stop) and for collecting eMBMS relatedcharging information.

The core network 190 may include an Access and Mobility ManagementFunction (AMF) 192, other AMFs 193, a Session Management Function (SMF)194, and a User Plane Function (UPF) 195. The AMF 192 may be incommunication with a Unified Data Management (UDM) 196. The AMF 192 isthe control node that processes the signaling between the UEs 104 andthe core network 190. Generally, the AMF 192 provides QoS flow andsession management. All user Internet protocol (IP) packets aretransferred through the UPF 195. The UPF 195 provides UE IP addressallocation as well as other functions. The UPF 195 is connected to theIP Services 197. The IP Services 197 may include the Internet, anintranet, an IP Multimedia Subsystem (IMS), a Packet Switch (PS)Streaming (PSS) Service, and/or other IP services.

The base station may include and/or be referred to as a gNB, Node B,eNB, an access point, a base transceiver station, a radio base station,a radio transceiver, a transceiver function, a basic service set (BSS),an extended service set (ESS), a transmit reception point (TRP), or someother suitable terminology. The base station 102 provides an accesspoint to the EPC 160 or core network 190 for a UE 104. Examples of UEs104 include a cellular phone, a smart phone, a session initiationprotocol (SIP) phone, a laptop, a personal digital assistant (PDA), asatellite radio, a global positioning system, a multimedia device, avideo device, a digital audio player (e.g., MP3 player), a camera, agame console, a tablet, a smart device, a wearable device, a vehicle, anelectric meter, a gas pump, a large or small kitchen appliance, ahealthcare device, an implant, a sensor/actuator, a display, or anyother similar functioning device. Some of the UEs 104 may be referred toas IoT devices (e.g., parking meter, gas pump, toaster, vehicles, heartmonitor, etc.). The UE 104 may also be referred to as a station, amobile station, a subscriber station, a mobile unit, a subscriber unit,a wireless unit, a remote unit, a mobile device, a wireless device, awireless communications device, a remote device, a mobile subscriberstation, an access terminal, a mobile terminal, a wireless terminal, aremote terminal, a handset, a user agent, a mobile client, a client, orsome other suitable terminology.

Referring again to FIG. 1 , in certain aspects, the UE 104 may include abarring component 198 that may be configured to receive, from at leastone cell via at least one bit in a MIB or a SIB, a barring indicationbased on a supported network of the at least one cell and a supportednetwork of the UE. The supported network of the cell may correspond to aTN or an NTN, and the supported network of the at least one UE maycorrespond to a TN or an NTN. The barring component 198 may beconfigured to skip, based on the received barring indication, aselection of the at least one cell for communication. In certainaspects, the base station/cell 180 may include a barring component 199that may be configured to determine whether to bar at least one UE fromselecting the cell for communication based on a supported network of thecell and a supported network of the at least one UE. The supportednetwork of the cell may correspond to a TN or an NTN, and the supportednetwork of the at least one UE may correspond to a TN or an NTN. Thebarring component 199 may be configured to transmit, to the at least oneUE via at least one bit in a MIB or a SIB, a barring indication based onthe supported network of the cell and the supported network of the atleast one UE. The barring component 199 may be configured to bar, basedon the transmitted barring indication, the at least one UE fromselecting the cell for communication. Although the following descriptionmay be focused on 5G NR, the concepts described herein may be applicableto other similar areas, such as LTE, LTE-A, CDMA, GSM, and otherwireless technologies

FIG. 2A is a diagram 200 illustrating an example of a first subframewithin a 5G NR frame structure. FIG. 2B is a diagram 230 illustrating anexample of DL channels within a 5G NR subframe. FIG. 2C is a diagram 250illustrating an example of a second subframe within a 5G NR framestructure. FIG. 2D is a diagram 280 illustrating an example of ULchannels within a 5G NR subframe. The 5G NR frame structure may befrequency division duplexed (FDD) in which for a particular set ofsubcarriers (carrier system bandwidth), subframes within the set ofsubcarriers are dedicated for either DL or UL, or may be time divisionduplexed (TDD) in which for a particular set of subcarriers (carriersystem bandwidth), subframes within the set of subcarriers are dedicatedfor both DL and UL. In the examples provided by FIGS. 2A, 2C, the 5G NRframe structure is assumed to be TDD, with subframe 4 being configuredwith slot format 28 (with mostly DL), where D is DL, U is UL, and F isflexible for use between DL/UL, and subframe 3 being configured withslot format 1 (with all UL). While subframes 3, 4 are shown with slotformats 1, 28, respectively, any particular subframe may be configuredwith any of the various available slot formats 0-61. Slot formats 0, 1are all DL, UL, respectively. Other slot formats 2-61 include a mix ofDL, UL, and flexible symbols. UEs are configured with the slot format(dynamically through DL control information (DCI), orsemi-statically/statically through radio resource control (RRC)signaling) through a received slot format indicator (SFI). Note that thedescription infra applies also to a 5G NR frame structure that is TDD.

Other wireless communication technologies may have a different framestructure and/or different channels. A frame (10 ms) may be divided into10 equally sized subframes (1 ms). Each subframe may include one or moretime slots. Subframes may also include mini-slots, which may include 7,4, or 2 symbols. Each slot may include 7 or 14 symbols, depending on theslot configuration. For slot configuration 0, each slot may include 14symbols, and for slot configuration 1, each slot may include 7 symbols.The symbols on DL may be cyclic prefix (CP) orthogonal frequencydivision multiplexing (OFDM) (CP-OFDM) symbols. The symbols on UL may beCP-OFDM symbols (for high throughput scenarios) or discrete Fouriertransform (DFT) spread OFDM (DFT-s-OFDM) symbols (also referred to assingle carrier frequency-division multiple access (SC-FDMA) symbols)(for power limited scenarios; limited to a single stream transmission).The number of slots within a subframe is based on the slot configurationand the numerology. For slot configuration 0, different numerologies μ 0to 4 allow for 1, 2, 4, 8, and 16 slots, respectively, per subframe. Forslot configuration 1, different numerologies 0 to 2 allow for 2, 4, and8 slots, respectively, per subframe. Accordingly, for slot configuration0 and numerology μ, there are 14 symbols/slot and 2^(μ) slots/subframe.The subcarrier spacing and symbol length/duration are a function of thenumerology. The subcarrier spacing may be equal to 2^(μ)*15 kHz, where μis the numerology 0 to 4. As such, the numerology μ=0 has a subcarrierspacing of 15 kHz and the numerology μ=4 has a subcarrier spacing of 240kHz. The symbol length/duration is inversely related to the subcarrierspacing. FIGS. 2A-2D provide an example of slot configuration 0 with 14symbols per slot and numerology μ=2 with 4 slots per subframe. The slotduration is 0.25 ms, the subcarrier spacing is 60 kHz, and the symbolduration is approximately 16.67 μs. Within a set of frames, there may beone or more different bandwidth parts (BWPs) (see FIG. 2B) that arefrequency division multiplexed. Each BWP may have a particularnumerology.

A resource grid may be used to represent the frame structure. Each timeslot includes a resource block (RB) (also referred to as physical RBs(PRBs)) that extends 12 consecutive subcarriers. The resource grid isdivided into multiple resource elements (REs). The number of bitscarried by each RE depends on the modulation scheme.

As illustrated in FIG. 2A, some of the REs carry reference (pilot)signals (RS) for the UE. The RS may include demodulation RS (DM-RS)(indicated as R for one particular configuration, but other DM-RSconfigurations are possible) and channel state information referencesignals (CSI-RS) for channel estimation at the UE. The RS may alsoinclude beam measurement RS (BRS), beam refinement RS (BRRS), and phasetracking RS (PT-RS).

FIG. 2B illustrates an example of various DL channels within a subframeof a frame. The physical downlink control channel (PDCCH) carries DCIwithin one or more control channel elements (CCEs) (e.g., 1, 2, 4, 8, or16 CCEs), each CCE including six RE groups (REGs), each REG including 12consecutive REs in an OFDM symbol of an RB. A PDCCH within one BWP maybe referred to as a control resource set (CORESET). A UE is configuredto monitor PDCCH candidates in a PDCCH search space (e.g., common searchspace, UE-specific search space) during PDCCH monitoring occasions onthe CORESET, where the PDCCH candidates have different DCI formats anddifferent aggregation levels. Additional BWPs may be located at greaterand/or lower frequencies across the channel bandwidth. A primarysynchronization signal (PSS) may be within symbol 2 of particularsubframes of a frame. The PSS is used by a UE 104 to determinesubframe/symbol timing and a physical layer identity. A secondarysynchronization signal (SSS) may be within symbol 4 of particularsubframes of a frame. The SSS is used by a UE to determine a physicallayer cell identity group number and radio frame timing. Based on thephysical layer identity and the physical layer cell identity groupnumber, the UE can determine a physical cell identifier (PCI). Based onthe PCI, the UE can determine the locations of the aforementioned DM-RS.The physical broadcast channel (PBCH), which carries a masterinformation block (MIB), may be logically grouped with the PSS and SSSto form a synchronization signal (SS)/PBCH block (also referred to as SSblock (SSB)). The MIB provides a number of RBs in the system bandwidthand a system frame number (SFN). The physical downlink shared channel(PDSCH) carries user data, broadcast system information not transmittedthrough the PBCH such as system information blocks (SIBs), and pagingmessages.

As illustrated in FIG. 2C, some of the REs carry DM-RS (indicated as Rfor one particular configuration, but other DM-RS configurations arepossible) for channel estimation at the base station. The UE maytransmit DM-RS for the physical uplink control channel (PUCCH) and DM-RSfor the physical uplink shared channel (PUSCH). The PUSCH DM-RS may betransmitted in the first one or two symbols of the PUSCH. The PUCCHDM-RS may be transmitted in different configurations depending onwhether short or long PUCCHs are transmitted and depending on theparticular PUCCH format used. The UE may transmit sounding referencesignals (SRS). The SRS may be transmitted in the last symbol of asubframe. The SRS may have a comb structure, and a UE may transmit SRSon one of the combs. The SRS may be used by a base station for channelquality estimation to enable frequency-dependent scheduling on the UL.

FIG. 2D illustrates an example of various UL channels within a subframeof a frame. The PUCCH may be located as indicated in one configuration.The PUCCH carries uplink control information (UCI), such as schedulingrequests, a channel quality indicator (CQI), a precoding matrixindicator (PMI), a rank indicator (RI), and hybrid automatic repeatrequest (HARD) acknowledgment (ACK) (HARQ-ACK) information (ACK/negativeACK (NACK)) feedback. The PUSCH carries data, and may additionally beused to carry a buffer status report (BSR), a power headroom report(PHR), and/or UCI.

FIG. 3 is a block diagram of a base station 310 in communication with aUE 350 in an access network. In the DL, IP packets from the EPC 160 maybe provided to a controller/processor 375. The controller/processor 375implements layer 3 and layer 2 functionality. Layer 3 includes a radioresource control (RRC) layer, and layer 2 includes a service dataadaptation protocol (SDAP) layer, a packet data convergence protocol(PDCP) layer, a radio link control (RLC) layer, and a medium accesscontrol (MAC) layer. The controller/processor 375 provides RRC layerfunctionality associated with broadcasting of system information (e.g.,MIB, SIBs), RRC connection control (e.g., RRC connection paging, RRCconnection establishment, RRC connection modification, and RRCconnection release), inter radio access technology (RAT) mobility, andmeasurement configuration for UE measurement reporting; PDCP layerfunctionality associated with header compression/decompression, security(ciphering, deciphering, integrity protection, integrity verification),and handover support functions; RLC layer functionality associated withthe transfer of upper layer packet data units (PDUs), error correctionthrough ARQ, concatenation, segmentation, and reassembly of RLC servicedata units (SDUs), re-segmentation of RLC data PDUs, and reordering ofRLC data PDUs; and MAC layer functionality associated with mappingbetween logical channels and transport channels, multiplexing of MACSDUs onto transport blocks (TBs), demultiplexing of MAC SDUs from TBs,scheduling information reporting, error correction through HARQ,priority handling, and logical channel prioritization.

The transmit (TX) processor 316 and the receive (RX) processor 370implement layer 1 functionality associated with various signalprocessing functions. Layer 1, which includes a physical (PHY) layer,may include error detection on the transport channels, forward errorcorrection (FEC) coding/decoding of the transport channels,interleaving, rate matching, mapping onto physical channels,modulation/demodulation of physical channels, and MIMO antennaprocessing. The TX processor 316 handles mapping to signalconstellations based on various modulation schemes (e.g., binaryphase-shift keying (BPSK), quadrature phase-shift keying (QPSK),M-phase-shift keying (M-PSK), M-quadrature amplitude modulation(M-QAM)). The coded and modulated symbols may then be split intoparallel streams. Each stream may then be mapped to an OFDM subcarrier,multiplexed with a reference signal (e.g., pilot) in the time and/orfrequency domain, and then combined together using an Inverse FastFourier Transform (IFFT) to produce a physical channel carrying a timedomain OFDM symbol stream. The OFDM stream is spatially precoded toproduce multiple spatial streams. Channel estimates from a channelestimator 374 may be used to determine the coding and modulation scheme,as well as for spatial processing. The channel estimate may be derivedfrom a reference signal and/or channel condition feedback transmitted bythe UE 350. Each spatial stream may then be provided to a differentantenna 320 via a separate transmitter 318 TX. Each transmitter 318 TXmay modulate an RF carrier with a respective spatial stream fortransmission.

At the UE 350, each receiver 354 RX receives a signal through itsrespective antenna 352. Each receiver 354 RX recovers informationmodulated onto an RF carrier and provides the information to the receive(RX) processor 356. The TX processor 368 and the RX processor 356implement layer 1 functionality associated with various signalprocessing functions. The RX processor 356 may perform spatialprocessing on the information to recover any spatial streams destinedfor the UE 350. If multiple spatial streams are destined for the UE 350,they may be combined by the RX processor 356 into a single OFDM symbolstream. The RX processor 356 then converts the OFDM symbol stream fromthe time-domain to the frequency domain using a Fast Fourier Transform(FFT). The frequency domain signal comprises a separate OFDM symbolstream for each subcarrier of the OFDM signal. The symbols on eachsubcarrier, and the reference signal, are recovered and demodulated bydetermining the most likely signal constellation points transmitted bythe base station 310. These soft decisions may be based on channelestimates computed by the channel estimator 358. The soft decisions arethen decoded and deinterleaved to recover the data and control signalsthat were originally transmitted by the base station 310 on the physicalchannel. The data and control signals are then provided to thecontroller/processor 359, which implements layer 3 and layer 2functionality.

The controller/processor 359 can be associated with a memory 360 thatstores program codes and data. The memory 360 may be referred to as acomputer-readable medium. In the UL, the controller/processor 359provides demultiplexing between transport and logical channels, packetreassembly, deciphering, header decompression, and control signalprocessing to recover IP packets from the EPC 160. Thecontroller/processor 359 is also responsible for error detection usingan ACK and/or NACK protocol to support HARQ operations.

Similar to the functionality described in connection with the DLtransmission by the base station 310, the controller/processor 359provides RRC layer functionality associated with system information(e.g., MIB, SIBs) acquisition, RRC connections, and measurementreporting; PDCP layer functionality associated with headercompression/decompression, and security (ciphering, deciphering,integrity protection, integrity verification); RLC layer functionalityassociated with the transfer of upper layer PDUs, error correctionthrough ARQ, concatenation, segmentation, and reassembly of RLC SDUs,re-segmentation of RLC data PDUs, and reordering of RLC data PDUs; andMAC layer functionality associated with mapping between logical channelsand transport channels, multiplexing of MAC SDUs onto TBs,demultiplexing of MAC SDUs from TBs, scheduling information reporting,error correction through HARQ, priority handling, and logical channelprioritization.

Channel estimates derived by a channel estimator 358 from a referencesignal or feedback transmitted by the base station 310 may be used bythe TX processor 368 to select the appropriate coding and modulationschemes, and to facilitate spatial processing. The spatial streamsgenerated by the TX processor 368 may be provided to different antenna352 via separate transmitters 354TX. Each transmitter 354TX may modulatean RF carrier with a respective spatial stream for transmission.

The UL transmission is processed at the base station 310 in a mannersimilar to that described in connection with the receiver function atthe UE 350. Each receiver 318RX receives a signal through its respectiveantenna 320. Each receiver 318RX recovers information modulated onto anRF carrier and provides the information to a RX processor 370.

The controller/processor 375 can be associated with a memory 376 thatstores program codes and data. The memory 376 may be referred to as acomputer-readable medium. In the UL, the controller/processor 375provides demultiplexing between transport and logical channels, packetreassembly, deciphering, header decompression, control signal processingto recover IP packets from the UE 350. IP packets from thecontroller/processor 375 may be provided to the EPC 160. Thecontroller/processor 375 is also responsible for error detection usingan ACK and/or NACK protocol to support HARQ operations.

At least one of the TX processor 368, the RX processor 356, and thecontroller/processor 359 may be configured to perform aspects inconnection with 198 of FIG. 1 .

At least one of the TX processor 316, the RX processor 370, and thecontroller/processor 375 may be configured to perform aspects inconnection with 199 of FIG. 1 .

FIG. 4 is a diagram illustrating an example environment 400. In an NTN,an NTN cell, such as the first cell 404, may be enabled by acommunication satellite, such as the communication satellite/spacevehicle 402. A TN cell (e.g., the second cell 408) may be enabled by aterrestrial base station (e.g., the base station 406). The space vehicleenabling the NTN cell may be one of a high altitude pseudo-satellite(HAPS), a low earth orbit (LEO) satellite, a medium earth orbit (MEO)satellite, or a geostationary (GEO) satellite. An NTN cell may be amoving cell that may move as the space vehicle moves across the sky.Alternatively, the space vehicle may steer the transmit and receivebeams as the space vehicle moves across the sky such that the NTN cellenabled on and near the surface of the earth is fixed relative to theearth. A fixed NTN cell may also be enabled by a GEO satellite.

It may be advantageous to inform the UE whether the network is a TN oran NTN no later than the reception of a SIB 1. The TN cells and the NTNcells may be deployed in the same band over a same geographical area,and absent additional indications, a UE 410A, 410B may detect and campon a cell that is not suitable for the UE. For example, a UE 410A thatis expected to communicate with and camp on a TN cell and does notsupport an NTN cell (which may be referred to herein as a TN-supportingUE) may inappropriately detect and camp on an NTN cell. This may occuras existing TN-supporting UEs may not understand newly introduced fieldsor parameters (e.g., the satellite specific parameters) in the MIB orthe SIB, and may ignore the newly introduced fields or parameters andcamp inappropriately on the NTN cell. Similarly, a UE 410B that isexpected to communicate with and camp on an NTN cell (which may bereferred to herein as an NTN-supporting UE) may inappropriately detectand camp on a TN cell. Therefore, it may be beneficial for an NTN cellto bar TN-supporting UEs but not NTN-supporting UEs, and for a TN cellto bar NTN-supporting UEs but not TN-supporting UEs.

FIG. 5 illustrates a communication flow 500 of a wireless communicationsystem. At 506, the cell 504 may determine whether to bar at least oneUE 502 from selecting the cell 504 for communication based on asupported network of the cell 504 and a supported network of the atleast one UE 502. The supported network of the cell may correspond to aTN or an NTN, and the supported network of the at least one UE maycorrespond to a TN or an NTN.

At 508, the cell 504 may transmit to the at least one UE 502, and the UE502 may receive, from at least one cell 504, via at least one bit in aMIB or a SIB, a barring indication based on the supported network of thecell 504 and the supported network of the at least one UE 502.

At 510, the UE 502 may skip, based on the received barring indication, aselection of the at least one cell 504 for communication. At 512, thecell 504 may bar, based on the transmitted barring indication, the atleast one UE 502 from selecting the cell 504 for communication.

In one configuration, the communication may correspond to the at leastone UE 502 camping on the cell 504. Therefore, once barred from the cell504, the UE 502 may not camp on the cell 504.

In one configuration, the at least one UE 502 may be barred fromselecting the cell 504 for communication for a time period (e.g., 300s). This may be useful for a temporary barring of NTN access. The barmay end after the time period expires, and the UE 502 may then considerthe cell 504 for cell reselection. When a LEO satellite enabled cell 504is barred for NTN access, a shorter barring duration (e.g., <300 s) maybe used based on the cell visibility duration (e.g., the cell size) orthe satellite revisit time.

In one configuration, the at least one UE may be barred from selectingthe cell for communication for a duration of the UE storing informationabout barring access to the cell, and the information about barringaccess to the cell includes at least one of a physical cell identifier(PCID) or a frequency of the cell. Thus, if the cell 504 is barred forNTN-supporting UEs 502 for NTN access, the cell 504 is accessible toTN-supporting UEs 502 but not to NTN-supporting UEs 502. Conversely, ifthe cell 504 is barred for TN-supporting UEs 502 for TN access, the cell504 is accessible to NTN-supporting UEs 502 but not to TN-supporting UEs502.

In one configuration, a TN-supporting UE of the at least one UE may bebarred from selecting the cell for communication when the cell is anNTN-supporting cell, and an NTN-supporting UE of the at least one UE maybe barred from selecting the cell for communication when the cell is aTN-supporting cell.

In one configuration, NTN-supporting UEs may ignore the legacy barringindication in the MIB (e.g., the first barring indication in the MIB,the “cellBarred” parameter in the MIB), and TN-supporting UEs may followthe legacy barring indication in the MIB (e.g., the first barringindication in the MIB) as normal. A spare bit in the MIB may be used tointroduce a new NTN-specific barring indication (e.g., the secondbarring indication in the MIB) that may be applicable to NTN-supportingUEs or NTN access but not to TN-supporting UEs. Therefore, whether NTNaccess is barred for NTN-supporting UEs may be based on the newNTN-specific barring indication (e.g., the second barring indication inthe MIB). In particular, for example, if the second barring indicationin the MIB is set to 0, NTN-supporting UEs may be barred (including in acell with a conventional TN base station). If the second barringindication in the MIB is set to 1, NTN access by NTN-supporting UEs maybe allowed. In another example, the bit definition of the second barringindication in the MIB may be reversed. The TN-supporting UEs in the TNaccess mode may still use the legacy barring indication in the MIB andmay ignore the new NTN-specific barring indication in the MIB.Accordingly, a UE (whether a TN-supporting UE or an NTN-supporting UE)may learn the cell type (e.g., whether the cell is barred or allowed)from the MIB without acquiring the SIB 1, and power may be saved. Thisconfiguration may be applicable to NR. Accordingly, a TN-supporting UE502 may be barred or not barred from selecting the cell 504 forcommunication based on a first barring indication in the MIB regardlessof a second barring indication in the MIB, and an NTN-supporting UE 502may be barred or not barred from selecting the cell 504 forcommunication based on the second barring indication in the MIBregardless of the first barring indication in the MIB.

In one configuration, a reserved bit in the MIB may be used to introducea cell type indication. In another configuration, an existing bit in theMIB may be repurposed to introduce the cell type indication. Forexample, a bit value of 0 at the cell type indication may indicate a TNcell type, and bit value of 1 may indicate an NTN cell type. In anotherexample, the bit definition of the cell type indication may be reversed.An indication of a TN cell type may bar NTN-supporting UEs from access.The existing barring indication in the SIB 1 (e.g., the third barringindication in the SIB 1, the “Unified Access Barring (UAC)-BarringInformation” in the SIB 1) may be used as normal by NTN-supporting UEs(and by TN-supporting UEs). This configuration may be applicable toenhanced machine type communication (eMTC) or narrowband (NB)-internetof things (IoT) (NB-IoT). Accordingly, the MIB may include a cell typeindication indicative of the cell 504 as being either a TN-supportingcell or an NTN-supporting cell, and an NTN-supporting UE 502 may bebarred or not barred from selecting the cell for communication based onthe cell type indication and a third barring indication in a SIB 1. TheNTN-supporting UE 502 may be barred from selecting the cell 504 forcommunication based on the cell type indication indicative of the cellas being a TN-supporting cell.

In one configuration, a reserved bit in the MIB may be used to introducea new barring indication (e.g., a fourth barring indication in the MIB).For example, a bit value of 0 at the fourth barring indication mayindicate the cell is barred (e.g., existing or eNB TN type cell may barNTN-supporting UEs), and a bit value of 1 may indicate the cell is notbarred. In another example, the bit definition of the fourth barringindication may be reversed. The existing barring indication in the SIB 1(e.g., the third barring indication in the SIB 1; the “Unified AccessBarring (UAC)-Barring Information” in the SIB 1) may be used byTN-supporting UEs or existing UEs but not by NTN-supporting UEs (e.g.,the NTN-supporting UEs may ignore the existing barring indication in theSIB 1). This configuration may be applicable to eMTC or NB-IoT.Accordingly, a TN-supporting UE 502 may be barred or not barred fromselecting the cell 504 for communication based on a third barringindication in a SIB 1 regardless of a fourth barring indication in theMIB, and an NTN-supporting UE 502 may be barred or not barred fromselecting the cell 504 for communication based on the fourth barringindication in the MIB regardless of the third barring indication in theSIB 1.

In one configuration, for eMTC, the “phich-Config” parameter in the MIBmay be repurposed for indicating a cell type or a cell barringindication. In one configuration, for eMTC, a whole MIB (e.g., theMasterInformationBlock-MBMS-r14 block) may be repurposed for the NTNaccess.

In one configuration, the barring indication in the MIB (e.g., the firstbarring indication in the MIB, the “cellBarred” parameter in the MIB)may be applicable to NTN-supporting UEs for NTN access. The firstbarring indication in the MIB may be applicable to all UEs, bothTN-supporting and NTN-supporting. In addition, if the“ssb-SubcarrierOffset” parameter in the MIB indicates that this celldoes not provide a SIB 1, the indication may mean that the cell isbarred for NTN access (but not for TN access) even if the existingbarring indication (e.g., the first barring indication in the MIB, the“cellBarred” parameter in the MIB) does not indicate a bar.Alternatively, if the MIB is not associated with an SSB, then the cellmay be considered barred for NTN access. This configuration may beapplicable to NR. Accordingly, a TN-supporting UE 502 may be barred ornot barred from selecting the cell 504 for communication based on afirst barring indication in the MIB, and an NTN-supporting UE 502 may bebarred or not barred from selecting the cell 504 for communication basedon the first barring indication in the MIB and at least one additionalindication in the MIB. The NTN-supporting UE 502 may be barred fromselecting the cell 504 for communication based on the first barringindication in the MIB indicative of a bar or the at least one additionalindication in the MIB indicative of an absence of a SIB 1 in the cell504.

In one configuration, one or more parameters may be used together todetermine whether the cell is barred or not barred for NTN-supportingUEs. The “cellBarred” parameter in the MIB (e.g., the first barringindication in the MIB) alone may not be sufficient to bar NTN-supportingUEs for NTN access. NT-supporting UEs may follow the “cellBarred”parameter in the MIB (e.g., the first barring indication in the MIB) asnormal. NTN-supporting UEs may not be barred when the “cellBarred”parameter in the MIB (e.g., the first barring indication in the MIB)does not indicate a bar. Further, one or more additional parameters,e.g., a spare bit, the “intraFreqReselection” parameter, the“pdcch-ConfigSIB1” parameter, or the “ssb-SubcarrierOffset” parameter inthe MIB may be used to indicate whether NTN-supporting UEs are barredwhen the “cellBarred” parameter in the MIB (e.g., the first barringindication in the MIB) does indicate a bar. For example, the“cellBarred” parameter may indicate a bar and the field“ssb-SubcarrierOffset” may indicate that the SIB 1 is absent, thenNTN-supporting UEs may be barred from accessing the cell. In anotherexample, when the “cellBarred” parameter indicate a bar, whetherNTN-supporting UEs are barred or allowed may be based on the value of anew indication introduced using a spare bit in the MIB. For example,NTN-supporting UEs may be barred when the new indication is set to 0,and may be allowed when the new indication is set to 1. In anotherexample, the bit definition of the new indication in the MIB may bereversed. If an NTN-supporting UE finds both an NTN cell and a TN cell,the NTN-supporting UE may prioritize the selection of the TN cell overthe NTN cell. If a TN cell (e.g., an existing cell) indicates cellbarring via the “cellBarred” parameter in the MIB (e.g., the firstbarring indication in the MIB), then the TN cell may not be barred forall UEs (TN-supporting UEs and NTN-supporting UEs) (e.g., TN-supportingUEs may be barred, whereas NTN-supporting UEs may be allowed). In otherwords, a TN cell may not selectively bar TN-supporting UEs orNTN-supporting UEs, but an NTN cell may selectively bar TN-supportingUEs or NTN-supporting UEs. This configuration may be applicable to NR.Accordingly, a TN-supporting UE 502 may be barred or not barred fromselecting the cell 504 for communication based on a first barringindication in the MIB, and an NTN-supporting UE 502 may be barred or notbarred from selecting the cell 504 for communication based on at leastone additional indication in the MIB when the first barring indicationin the MIB indicates a bar. The NTN-supporting UE 502 may not be barredfrom selecting the cell 504 for communication when the first barringindication in the MIB does not indicate a bar. The NTN-supporting UE 502may be barred from selecting the cell 504 for communication based on theat least one additional indication in the MIB indicative of a bar ofNTN-supporting UEs when the first barring indication in the MIBindicates a bar.

In one configuration, the barring indication in MIB (e.g., the firstbarring indication in the MIB, the “cellBarred” parameter in the MIB)may be ignored by NTN-supporting UEs for NTN access. In other words, thefirst barring indication in the MIB may be applicable to legacy or TNaccess by TN-supporting UEs. If the SIB1 does not schedule a new NTNspecific SIB, or does not schedule a SIB that provides satellitespecific information (e.g., ephemeris), the cell may be barred forNTN-supporting UEs or NTN access. Accordingly, a TN-supporting UE 502may be barred or not barred from selecting the cell 504 forcommunication based on a first barring indication in the MIB, and anNTN-supporting UE 502 may be barred or not barred from selecting thecell 504 for communication based on a SIB 1 regardless of the firstbarring indication in the MIB. The NTN-supporting UE 502 may be barredfrom selecting the cell 504 for communication based on the SIB 1 notscheduling at least one additional SIB including NTN-related informationregardless of the first barring indication in the MIB.

In one configuration, the barring indication in MIB (e.g., the firstbarring indication in the MIB, the “cellBarred” parameter in the MIB)may be ignored by NTN-supporting UEs for NTN access. At least oneindication in the SIB 1, such as the “cellReservedForOperatorUse”parameter, the “cellReservedForOtherUse” parameter, or the“cellReservedForFutureUse” parameter indicated in the SIB 1 may be usedfor barring the NTN-supporting UEs for NTN access. Accordingly, theNTN-supporting UE 502 may be barred or not barred from selecting thecell 504 for communication based on an indication in the SIB 1regardless of the first barring indication in the MIB.

In one configuration, a TN-supporting UE 502 may be barred or not barredfrom selecting the cell 504 for communication based on a first barringindication in the MIB, and based further on the indication in the SIB 1(e.g., “cellReservedForOperatorUse” parameter, the“cellReservedForOtherUse” parameter, or the “cellReservedForFutureUse”parameter).

In one configuration, a new barring indication (e.g., a fifth barringindication in the SIB 1) for NTN-supporting UEs for NTN access may beintroduced in the SIB 1. Accordingly, an NTN-supporting UE 502 may bebarred or not barred from selecting the cell 504 for communication basedon the fifth barring indication in the SIB 1. The fifth barringindication in the SIB 1 may be indicative of whether at least one of NTNLEO access or NTN GEO access is barred.

In one configuration, the existing cell barring indication, the“cellBarred” parameter in the SIB 1 (e.g., the third barring indicationin the SIB 1) may be ignored by NTN-supporting UEs. A new barringindication (e.g., a fifth barring indication in the SIB 1) forNTN-supporting UEs for NTN access may be introduced in the SIB 1 (e.g.,a “cellBarredNTN-r1xa” parameter in the SIB 1). This configuration maybe applicable to eMTC or NB-IoT. Accordingly, a TN-supporting UE 502 maybe barred or not barred from selecting the cell 504 for communicationbased on a third barring indication in a SIB 1 regardless of a fifthbarring indication in the SIB 1, and an NTN-supporting UE 502 may bebarred or not barred from selecting the cell 504 for communication basedon the fifth barring indication in the SIB 1 regardless of the thirdbarring indication in the SIB 1.

FIG. 6 is a flowchart 600 of a method of wireless communication. Themethod may be performed by a UE (e.g., the UE 104/350/410/502; theapparatus 802). At 602, the UE may receive, from at least one cell viaat least one bit in a MIB or a SIB, a barring indication based on asupported network of the at least one cell and a supported network ofthe UE. The supported network of the cell may correspond to a TN or anNTN, and the supported network of the at least one UE may correspond toa TN or an NTN. For example, 602 may be performed by the barringcomponent 840 in FIG. 8 . Referring to FIG. 5 , at 508, the UE 502 mayreceive, from at least one cell 504 via at least one bit in a MIB or aSIB, a barring indication based on a supported network of the at leastone cell 504 and a supported network of the UE 502.

At 604, the UE may skip, based on the received barring indication, aselection of the at least one cell for communication. For example, 604may be performed by the barring component 840 in FIG. 8 . Referring toFIG. 5 , at 510, the UE 502 may skip, based on the received barringindication, a selection of the at least one cell 504 for communication.

In one configuration, the communication may correspond to the at leastone UE camping on the at least one cell. Referring to FIG. 5 , thecommunication may correspond to the at least one UE 502 camping on theat least one cell 504.

In one configuration, the at least one UE may be barred from selectingthe at least one cell for communication for a time period. The at leastone UE may select the at least one cell for communication after the timeperiod.

In one configuration, the at least one UE may be barred from selectingthe at least one cell for communication for a duration of the UE storinginformation about barring access to the at least one cell, and theinformation about barring access to the at least one cell may include atleast one of a PCID or a frequency of the at least one cell.

In one configuration, when the UE is a TN-supporting UE, the UE may bebarred from selecting the at least one cell for communication when theat least one cell is an NTN-supporting cell, and when the UE is anNTN-supporting UE, the UE may be barred from selecting the at least onecell for communication when the at least one cell is a TN-supportingcell.

In one configuration, the MIB may include a cell type indicationindicative of the at least one cell as being either a TN-supporting cellor an NTN-supporting cell, and when the UE is an NTN-supporting UE, theUE may be barred or not barred from selecting the at least one cell forcommunication based on the at least one cell type indication and a thirdbarring indication in a SIB 1, and the UE may be barred from selectingthe at least one cell for communication based on the at least one celltype indication indicative of the at least one cell as being aTN-supporting cell.

In one configuration, when the UE is a TN-supporting UE, the UE may bebarred or not barred from selecting the at least one cell forcommunication based on a third barring indication in a SIB 1 regardlessof a fourth barring indication in the MIB, and when the UE is anNTN-supporting UE, the UE may be barred or not barred from selecting theat least one cell for communication based on the fourth barringindication in the MIB regardless of the third barring indication in theSIB 1.

In one configuration, when the UE is a TN-supporting UE, the UE may bebarred or not barred from selecting the at least one cell forcommunication based on a first barring indication in the MIB, when theUE is an NTN-supporting UE, the UE may be barred or not barred fromselecting the at least one cell for communication based on the firstbarring indication in the MIB and at least one additional indication inthe MIB, and when the UE is the NTN-supporting UE, the UE may be barredfrom selecting the at least one cell for communication based on thefirst barring indication in the MIB indicative of a bar or the at leastone additional indication in the MIB indicative of an absence of a SIB 1in the at least one cell.

In one configuration, when the UE is a TN-supporting UE, the UE may bebarred or not barred from selecting the at least one cell forcommunication based on a first barring indication in the MIB, when theUE is an NTN-supporting UE, the UE may be barred or not barred fromselecting the at least one cell for communication based on at least oneadditional indication in the MIB when the first barring indication inthe MIB indicates a bar, and when the UE is the NTN-supporting UE, theUE may be barred from selecting the at least one cell for communicationbased on the at least one additional indication in the MIB indicative ofa bar of NTN-supporting UEs in the at least one cell when the firstbarring indication in the MIB indicates a bar.

In one configuration, when the UE is a TN-supporting UE, the UE may bebarred or not barred from selecting the at least one cell forcommunication based on a first barring indication in the MIB, and whenthe UE is an NTN-supporting UE, the UE may be barred or not barred fromselecting the at least one cell for communication based on a SIB 1regardless of the first barring indication in the MIB.

In one configuration, when the UE is the TN-supporting UE, the UE may bebarred or not barred from selecting the at least one cell forcommunication based further on the indication in the SIB 1.

In one configuration, the indication in the SIB 1 may be indicative ofwhether at least one of NTN LEO access or NTN GEO access is barred.

FIG. 7 is a flowchart 700 of a method of wireless communication. Themethod may be performed by a base station/cell (e.g., the basestation/cell 102/180/402/404/406/408/504; the apparatus 902). At 702,the cell may determine whether to bar at least one UE from selecting thecell for communication based on a supported network of the cell and asupported network of the at least one UE. The supported network of thecell may correspond to a TN or an NTN, and the supported network of theat least one UE may correspond to a TN or an NTN. For example, 702 maybe performed by the barring component 940 in FIG. 9 .
